One thousand three hundred years.
This time is not too long; rather, it is quite the opposite, it is too short.
After all, according to the intelligence gathered from the Association, Force One took over twenty-four million years to attempt to cross this level.
But they have never managed to cross over.
Yet the Association's time spent is nearly twenty thousand times shorter.
Of course, this is partly because the Association already controls a world beyond this level and has detailed records of the laws.
But the true core reason lies in the Association's possession of the Gray Mist Space.
After all, long durations are often stuck at certain stages.
And the Gray Mist within the Gray Mist Space can help the Association quickly cross some critical stages.
This acceleration effect is the coveted aid in the development process of civilizations and forces.
However, even so, one thousand three hundred years is still a bit too long for the Association.
